Image Gallery with PhotoSwipe

In one of my recent projects(image-tweaker), I provided users with the ability to upload images, which were then displayed in a collection on the dashboard. I was searching for a way to give these images a cool animated view, and that's when I discovered PhotoSwipe!

PhotoSwipe is a powerful, easy-to-use JavaScript library that allows you to create beautiful, animated image galleries. It provides a smooth and responsive experience, making your image collections look stunning on any device.

Let's make an image gallery in React with the react-photoswipe-gallery.

#Let's Start by Bootstrapping a Fresh React-TS App

npm create vite@latest react-app-gallery -- --template react
cd react-app-gallery
npm install
npm run dev

And just like that, we have our plain Vite React app ready to go!

This will set up a new React project with TypeScript support. You should see a default Vite React app running at http://localhost:3000.

#Clean Up the Default Setup

You can also remove the default CSS in App.css and index.css.

export default function App() {
  return <div>App</div>;
}

#Adding PhotoSwipe

Now let's start adding the dependencies

npm i react-photoswipe-gallery photoswipe

Include the CSS file from photoswipe. (As a best practice, I typically add these types of default CSS files in main.tsx.)

import "photoswipe/dist/photoswipe.css";

#Creating the Image Gallery

Now, let's create a simple image gallery using react-photoswipe-gallery. Update App.tsx with the following code:

Add some images and include their links in App.tsx, like this:

import Image1 from "./assets/image1.png";
import Image2 from "./assets/image2.png";
import Image3 from "./assets/image3.png";

make an array of images(you can use external links as well)

const images = [Image1, Image2, Image3];

Now, to add the photoswipe gallery, let's wrap the images in Gallery.

import { Gallery, Item } from "react-photoswipe-gallery";

import Image1 from "./assets/image1.png";
import Image2 from "./assets/image2.png";
import Image3 from "./assets/image3.png";

export default function App() {
  const images = [Image1, Image2, Image3];
  return <Gallery>// images here</Gallery>;
}

A single image inside the gallery looks like this:

<Item original={image} width="1024" height="768">
  {({ ref, open }) => (
    <img
      ref={ref}
      onClick={open}
      src={image}
      style={{
        width: "200px",
        height: "200px",
      }}
    />
  )}
</Item>;

This code creates an image item within a gallery using the react-photoswipe-gallery library. Here's a breakdown of this spooky code:

• <Item>: This is a component from the react-photoswipe-gallery library that represents a single image item in the gallery.
  • original={image}: This prop sets the original, full-size image source.
• {({ ref, open }) => (...)}: This is a render prop function that provides two arguments:
  • ref: A reference to the image element, used to track and manipulate the DOM element.
  • open: A function that opens the image in the gallery when called.

But we have an array of images, so we simply map the array

{
  images.map((image, index) => (
    <Item
      key={index}
      original={image}
      width="1024"
      height="768"
    >
      {({ ref, open }) => (
        <img
          ref={ref}
          onClick={open}
          src={image}
          style={{
            width: "200px",
            height: "200px",
          }}
        />
      )}
    </Item>
  ));
}

Currently, the image appears quite congested.

Just so as to add some breathing space let's add some styles

style={{
  width: "200px",
  height: "200px",
  margin: 10,
  cursor: "pointer",
  borderRadius: 10,
}}

And yes, it works fine now, here's the complete code

import { Gallery, Item } from "react-photoswipe-gallery";

import Image1 from "./assets/image1.png";
import Image2 from "./assets/image2.png";
import Image3 from "./assets/image3.png";

export default function App() {
  const images = [Image1, Image2, Image3];
  return (
    <Gallery>
      {images.map((image, index) => (
        <Item
          key={index}
          original={image}
          width="1024"
          height="768"
        >
          {({ ref, open }) => (
            <img
              ref={ref}
              onClick={open}
              src={image}
              style={{
                width: "200px",
                height: "200px",
                margin: 10,
                cursor: "pointer",
                borderRadius: 10,
              }}
            />
          )}
        </Item>
      ))}
    </Gallery>
  );
}

#Here's the final version!

With these changes, your image gallery should now look much cleaner and more user-friendly. The added margin and rounded corners give each image some breathing room and a polished appearance. Enjoy your improved gallery!
